HEIC to PNG Converter

This page is the HEIC converter with the output format already switched to PNG. You do not have to change any setting before you start, and the whole job takes place in your browser tab.

1. Drop your .heic or .heif files onto the box, paste them, or click the box to browse. You can add a whole batch in one go.
2. Look at the Convert to menu. It shows PNG. The JPG quality slider sits below it, but PNG ignores it, so there is nothing to tune.
3. Press Convert HEIC. The page loads its decoder the first time, then works through your photos one after another and reports progress as it goes.
4. Check the line under each thumbnail. It shows the original size, an arrow and the new size, so you can see how much bigger the PNG is.
5. Press Download beside a single picture, or Download all to save every result. IMG_2041.heic comes back as IMG_2041.png.

HEIC is a compressed format, and the encoder inside the phone already chose which fine detail to discard. Turning that file into a PNG does not undo this. What PNG does promise is that nothing more is lost: every pixel the decoder produces is stored exactly, so you can open, edit and save the PNG as many times as you like without the repeated softening that JPEG causes.

That promise has a price in file size. A typical iPhone photo is 4032 by 3024 pixels, which is about 12.2 million pixels. A HEIC of that picture may be around 2 MB. As a JPG at high quality it often lands near 3 to 5 MB, while a lossless PNG of a detailed scene commonly runs from 15 MB to well over 20 MB. These are illustrations, not guarantees, and the tool prints the real figures for each file.

If you only want to send the picture to someone, the HEIC to JPG converter gives a far smaller file. Choose PNG when the next step is editing, not sending.

PNG is the better target in a few specific situations, and it is worth being clear about which ones apply to you.

• Editing in layers. If you will retouch, crop and re-export in a design program, starting from a lossless file keeps each save from adding artifacts.
• Screenshots and graphics from a phone. A photographed whiteboard or a picture of a printed page has hard edges, and PNG keeps those edges clean where JPG can smear them.
• Windows and other apps without HEIC support. Many programs read PNG without any extension or codec pack.
• Archiving. A PNG is a stable, widely documented container. If you want a working copy that will open in ten years, it is a safe choice.
• Transparency. PNG can store an alpha channel. Ordinary camera photos have none, so this matters only for the rare HEIC that carries one, and in that case the see-through areas stay see-through.

None of this is a reason to convert everything. Keep the original HEIC files as your master copies, since they are the smallest and hold what the camera recorded.

A folder of twenty PNG photos can easily pass half a gigabyte, which is awkward to email or upload. A few habits keep it manageable. Convert only the pictures you actually plan to edit. Reduce the pixel size afterward with the image resizer if the final use is a web page or a slide, since a 4032 pixel wide image is far more than a screen needs. Or switch the finished copy to a smaller format with the image converter, which can write JPEG and WebP as well as PNG.

The conversion discards camera metadata. The result line says that details such as GPS location are not copied, which is useful if you are about to post the picture. If you also have JPG or PNG files from other sources that still carry location data, the EXIF data remover handles those. Everything happens in your browser, so the originals never leave your phone or computer, and the first conversion may take a moment longer because the decoder has to load once.
